TRAININGMASK - 2.0 Turn Flow - Resistance Training Mask® - Fitness Mask, High Altitude Mask, Workout Mask

Works great.

Great mask that doesn't let a bunch of air blow into my eyes on every exhale. This one fits tightly over the bridge of my nose, and is made of thick durable material to ensures a tight seal. The version I bought came with a variety of seals and an over-head strap that provides plenty of customizable solutions for workouts, along with the dials that allow changes in resistance mid-workout. I greatly appreciate this decision to let the customer choose.

This is actually what I wanted... I have been watching Training Mask for a while; it is the perfect thing for work outs while I travel. It performs as expected, it seems to be high quality but the directions included in the box are kind of minimal (there is an extra elastic strap, for example, that I am not sure what to do with). If you plan to use this regularly, though, you probably will want to invest in a second "sleeve," the part that holds the mask to your face, so you can throw one in the washing machine without interrupting your workout schedule!

Lo que esperaba, me ha hace mejorar con la respiración y a expandir mis pulmones

This works, I live at sea level and went to Idaho and climbed to 10,500', I don't want to say I was 100% but this mask surely helped, it fit snug and had many options for elevation... loved it!

It fits pretty well and has the looks and the feel of a very well made product. However, it makes a lot of wheezing and high pitch noise that I’d be too embarrassed to wear it while working out. I just hope I can return it

Really dose help with stamina it dose come with a price of not really beathing able to breath while working out thats because it ment for that training and conditioning oxygenLevels in your breathing

I wore this on the hardest setting around the house while watching my toddler and doing random chores (running up and down stairs between levels of house) and it wasn't hard to breath in at all. I thought "man, this mask ain't sheet. I hope I didn't waste my money" I finally got the courage to wear it at the gym and holy crap I almost died! I highly recommend the twist valves. I didn't even have it on the hardest setting and I was on the treadmill with the incline at 15 then the speed about 4.7 when I had to open some of the holes. It takes some getting used to but once I got my breathing down I went a little faster but that was a big mistake. I started to take quick short breathes, had to open all holes but still wasn't enough air. At this point I started to panic a little bc I couldn't get my breathing back on track then I couldn't easily grab the velcro to remove the mask while running (this was a me thing not a product issue) so I started to breathe harder and the treadmill on a 15 incline restricted me from just jumping on the sides to stop running and focus on the mask. I was able to pry the bottom of the mask up and off my face to catch my breath. I have used it several more times since then and haven't had any issues. I can actually feel my lungs still expanded for a while after using. I gave 4 stars bc the head strap is tight. I am 5'2 110lb female and ordered the small. The suction is tight and it does hurt the bridge of nose if not sitting correctly.
